title: Dissipation and residue of rotenone in cabbage and soil under field conditions.
abstract: Rotenone dissipation and terminal residue in cabbage and soil under field conditions were determined by high-performance liquid chromatography. The dissipation rates of rotenone were described using first-order kinetics. The half-lives ranged from 0.89 to 1.55 days in cabbage and 1.98 to 2.76 days in soil. Prolonged pre-harvest interval times ensure that the cabbage is safe for consumption. Temperature and the physico-chemical properties of the soil were identified as the key factors affecting rotenone degradation in cabbage and soil under field conditions.
